CWEhttps://cwe.mitre.org/data/definitions/134.html

Format string vulnerability in the p_cgi_error function in python/neo_cgi.c in the Python CGI Kit (neo_cgi) module for Clearsilver 0.10.5 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via format string specifiers that are not properly handled when creating CGI error messages using the cgi_error API function.

Weakness

The product uses a function that accepts a format string as an argument, but the format string originates from an external source.
